ATF-2 is normally activated in response to signals that converge on stress-activated protein kinases p38 and JNK.

Satellite cells are normally activated upon injury or exercise.

At the higher antimitotic concentrations, paclitaxel appears to act by suppressing microtubule detachment from centrosomes, a process that is normally activated during mitosis.

Automatic bulk tank washing systems are used in closed tanks and are normally activated by the milk collection truck driver after each milk collection.

At the higher therapeutic concentrations, paclitaxel appears to suppress microtubule detachment from centrosomes, a process normally activated during mitosis.

Railroad crossing lights, which are normally activated by train engineers, were not working so the police blocked crossings with patrol cars.

The left ventricle however, is still normally activated by the left bundle branch.

Other genes that are normally activated by MeCP2 remain inactive and thus unable to make protein products.

This function is normally activated by an "E" terminal on the thermostat.
